Not all cases of employee data theft come from bad intentions. Lukasz Krupski’s journey at Tesla began heroically. His quick action as he tackled a fire hazard at a Norway Tesla exhibition won him praise from Elon Musk.

But after finding monitoring software on his laptop and being dismissed, Krupski felt compelled to leak safety and data protection concerns, known as the ‘Tesla Files,’ to the media. These leaks, which revealed employee and customer data alongside issues with Tesla’s technology, sparked widespread discussion and legal scrutiny.

Krupski’s actions, motivated by a desire to highlight serious safety concerns, have highlighted the ethical challenges and accountability in technology.

While his case might be somewhat heroic due to his motivations, it’s essential to remember that not all instances of employee data theft are for noble reasons; sometimes, they’re purely for personal gain.

As we explore the topic of preventing data theft by employees, it’s critical to differentiate between the motivations behind such actions and implement robust security measures to safeguard sensitive information.

Key takeaways

• Employee data theft involves staff taking or sharing company data without permission, posing risks to the company’s security and trust, whether done on purpose or by accident.

• The theft of sensitive data by employees can lead to financial losses, reputational damage, legal issues, operational disruptions, erosion of trust among team members, and unauthorized access to corporate accounts.

• To protect sensitive information and prevent data theft by employees, companies should implement robust access controls, use encryption for sensitive data, regularly conduct security training, and establish a clear data security policy.

• Enhancing data security further involves implementing MFA, securing physical access to facilities, using updated anti-malware and anti-phishing solutions, and adopting a Zero Trust security model that requires continuous verification of all users.

• NordLayer helps prevent employee data theft through advanced cybersecurity tools like Cloud Firewall and network access control solutions, which help achieve network segmentation and the Zero Trust framework.

What is employee data theft?

This can be intentional, as in cases where someone decides to steal sensitive information to sell or use against the company. Sometimes, it happens by mistake, like when an employee accidentally exposes information because they weren’t careful. No matter the intent, such theft is a big problem for a company’s safety and credibility.

The risk involves all sorts of sensitive data. This includes personal details about employees and customers, financial information, strategic documents, and passwords to corporate accounts.

There are many ways someone might steal corporate data, such as copying it to a personal device, sending it through unsecured emails, or using harmful software to sneak into a company’s systems.

Another well-known case that highlights the risks of employee data theft involves Anthony Levandowski. He was an engineer at Google’s Waymo, the self-driving car project. Before leaving, Levandowski took thousands of files about Google’s technology for autonomous vehicles. He then founded a self-driving truck company named Otto, which Uber bought soon after. This led to a major legal fight between Waymo and Uber, focusing on accusations that Uber benefited from the stolen secrets. This story shows why it’s so crucial to protect sensitive data.

Risks of data theft by employees

A data breach doesn’t just stop at the act of theft; it opens up a Pandora’s box of indirect risks. Here are some consequences companies can face when employees steal data.

1. Financial loss. When employees steal data, companies can face direct financial losses. This is because stolen sensitive information can lead to fraud or the loss of competitive advantage.

2. Reputational damage. A data breach caused by employee data theft can harm a company’s reputation. Customers and partners may lose trust, which is hard to rebuild.

3. Legal and regulatory issues. If employees take sensitive data, this can result in legal penalties for the company. This is especially true if the stolen information includes personal data protected by laws.

4. Loss of intellectual property. Corporate data theft can lead to the loss of proprietary information. This is a serious risk as it can give competitors an unfair advantage.

5. Operational disruptions. Data theft by employees can disrupt business operations. For example, if critical data is stolen, it might halt production or service delivery.

6. Increased security costs. To prevent employee data theft, companies may need to invest more in data security measures. This can include adopting a Zero Trust framework, which verifies every access request.

7. Erosion of employee trust. When corporate data theft occurs, it can create an environment of suspicion. This might reduce collaboration and trust among team members.

8. Access to corporate accounts. Employees who steal data might gain access to corporate accounts. This risk is particularly high with sensitive information that includes login credentials.

How to prevent employee data theft

The numbers tell us that sales and customer service roles are where we often find the biggest concerns for insider risks, with sales at 48% and customer service at 47%.

But really, keeping our data safe is a job for everyone in the company, not just designated roles. So, let’s explore some clever ways to protect your company.

Implement strong access controls

Setting up strong access controls, like a hardware or cloud firewall, and dividing the network into sections makes sure employees can only get to the data they need for work. This helps in preventing data theft by employees.

It’s important to remember that not everyone needs to see everything in the company. Making it clear what’s confidential can also help stop data from getting out by mistake.

A firewall helps divide the network into sections with clear permissions. This way, you limit who can see sensitive data, helping to avoid accidental sharing.

A cloud firewall (or a Firewall-as-a-Service) makes it easy to set up these divisions, giving specific access rights to certain people or groups. This is great for data security because it helps contain potential problems if something goes wrong. Thanks to how you’ve divided it, employees can only see a small part of the network. This means threat actors can’t do as much damage even if it’s an employee.

Use encryption for sensitive data

Encrypting sensitive data protects it, making the data unreadable to unauthorized users. This is effective even if data is stolen, as the thief cannot use it without the decryption key.

The downside is that managing encryption keys requires careful security measures to prevent them from being stolen as well.

Conduct regular security training

Educating employees about the importance of data security and how to prevent data theft is crucial. Regular training can make employees aware of the risks and teach them to handle data securely. But remember that training alone cannot prevent all instances of data theft, especially if malicious intent is involved.

Deploy data loss prevention (DLP) technology

Using data loss prevention, or DLP technology, is like having a smart security guard that watches over the information being shared in and out of the company. It makes sure that only the right data goes to the right places.

Think of it as having a guard who checks the passes at the door of a secure building. The guard stops people without the right pass (unauthorized data) from leaving.

But, just like any guard might sometimes stop someone by mistake (a false positive), DLP technology can accidentally block information that was okay to share. This means it’s really good at preventing data theft by employees, but it might need a little help sometimes to make sure it doesn’t stop the right information from getting through.

Establish a clear data security policy

A clear data security policy sets out rules for handling sensitive data and the consequences of data theft. This clarity helps prevent employee data theft by setting expectations. These policies must be regularly updated to remain effective and reflect new security challenges.

Implement multi-factor authentication (MFA)

Adding multi-factor authentication (MFA) to our security setup means we’re putting in place an extra step of verification, something more than just the usual password. This makes it much harder for someone to access data they shouldn’t.

If someone tries to sneak into an account or look at data they have no business seeing, MFA steps in. It sends a notification to either another employee or the person who owns the account, flagging that something out of the ordinary is happening.

This quick heads-up gives us a chance to act fast and stop any security problems before they grow, making MFA a really important tool in keeping our data safe.

Secure physical access to facilities

Make sure that only the right people can get into places where sensitive information or important servers are kept. This is especially important when you’ve got crucial servers in your office or when you’re dealing with sensitive data.

It’s essential to keep a close eye on who enters areas with critical data or infrastructure. Set up systems that check if someone is allowed in, like special locks or entry codes that only certain people have.

Use anti-malware and anti-phishing solutions

Adding anti-malware and anti-phishing software is a smart move to keep your data safe. But remember, these tools need to stay updated to fight off the latest cyber tricks. It’s also a good idea to teach your team how to spot those sneaky phishing emails. By keeping everything current and spreading a bit of know-how, you’re building a strong wall that keeps your data secure and out of the wrong hands.

Adopt a Zero Trust security model

The Zero Trust model operates on the principle that no one inside or outside the network is trusted by default. Implementing Zero Trust can significantly reduce the risk of data theft by requiring continuous verification of all users. However, moving to a Zero Trust architecture can be complex and requires significant adjustment for both IT departments and users.

No single method is foolproof, but a layered approach minimizes risks associated with employee data theft.

How NordLayer can protect against data theft by employees

NordLayer offers powerful cybersecurity tools, like Cloud Firewall and Network Access Control (NAC) solutions, to help your organization keep its sensitive data safe.

Network segmentation is an important part of the process. By breaking your network into smaller parts with strict access rules, you make sure only the right people can see important information. This is key to achieving the Zero Trust framework, which checks everyone’s need to access specific data, making it much harder for anyone to steal data or cause a breach. With NordLayer, setting up these secure sections in your network is straightforward and flexible.

Our Identity and Access Management (IAM) solutions add another layer of security by managing who gets access to what, beyond just passwords. The method combines Single Sign-On (SSO) with other checks to make sure every user’s sign-in is legit.

Other Network Access Control (NAC) solutions tighten security further by monitoring access based on IP addresses and device posture, allowing only compliant devices on the network. This approach offers a solid strategy on how to prevent data theft by employees.

Have you heard about the federal employee who browsed 9,000 adult sites in under 7 months? Between 2016 and 2017, this person used their work computer to access thousands of sites with explicit content. Many of these sites were linked to Russian pages that had malware.

On average, this meant visiting about 79 adult sites on each business day. This employee also stored a lot of explicit content on an unauthorized USB drive and their personal Android phone, both of which were connected to the work computer against the rules. The phone ended up getting infected with malware, according to the investigation.

This example highlights why blocking sites with adult-themed media is sensible. However, is it a good idea to block all types of inappropriate websites, such as social media? Would your employees see you as a tyrant, or could you adopt a Google-like approach that effectively improves security?

Let’s investigate whether blocking access to specific websites can benefit your company and how it might be perceived.

Key takeaways

• It’s important for businesses to learn how to stop employees from using non-work-related or harmful websites. This helps keep the workplace focused and safe, boosts productivity, and protects the company’s online assets.

• DNS filtering is a great way to keep employees away from sites they shouldn’t visit. It works by blocking certain internet requests, which helps reduce both distractions and security risks.

• Teaching employees why web filtering matters is key. It helps everyone understand why it keeps the company secure.

Why restrict internet access in a workplace?

Many businesses find it crucial to restrict internet access at work to boost productivity and secure their networks. Let’s explore the reasons and benefits of such restrictions.

• A key reason for limiting internet access is to enhance employee productivity. By blocking websites, especially social media and entertainment sites, companies can reduce distractions.

• Another vital reason is to protect the company’s network security. Accessing insecure websites can increase the risk of cyber threats such as malware, phishing attacks, and data breaches.

• It’s also important to manage bandwidth usage. Without restrictions, internet access might consume bandwidth for non-essential activities.

• Compliance with legal and regulatory standards is crucial. Accessing or downloading copyrighted material without permission, or engaging in other illegal online activities, could pose legal risks to the company. DNS filtering and web filtering block websites that could lead to legal issues.

• Lastly, maintaining a professional work environment involves blocking websites with inappropriate content, such as adult material or sites promoting hate or violence. This ensures a safe workplace where employees are not exposed to offensive content.

What websites should your business block access to?

Blocking websites effectively requires a clear strategy. Here’s a comprehensive list of the types of websites your business should consider blocking access to.

1. Phishing sites. These websites are crafted to deceive people into giving away personal or sensitive company information. They often mimic legitimate websites to steal data. Blocking access to known phishing sites is crucial for protecting your employees and your business.

2. Unofficial software download sites. While these sites may seem like a handy resource for free software, they frequently harbor security risks. These can include malware or software that infringes on copyright laws. Block these sites to protect your network and comply with intellectual property regulations.

3. File sharing and torrent sites. These platforms are notorious for spreading malware and facilitating data breaches. By blocking these sites, you significantly reduce the risk of infecting your company’s systems with malicious software.

4. Social media platforms. Well, it’s no secret that social media can be a major distraction in the workplace. Block social media platforms to increase productivity.

5. Video streaming services. High bandwidth usage from streaming services can slow down your network and affect the performance of work-critical applications. Blocking these services ensures that your internet bandwidth is reserved for business operations.

6. Online gaming sites. Similar to social media, online games can divert employees’ attention from their work. DNS filtering can prevent access to gaming websites, helping employees stay on track.

7. Adult content websites. Restrict access to websites with adult content to maintain a respectful and comfortable work environment for everyone, beyond the obvious professional and security reasons.

8. Online shopping sites. While convenient for personal use, these sites can distract employees during work hours. Block access to e-commerce platforms to keep the focus on work.

9. Gambling websites. Block access to gambling sites to maintain professionalism and prevent potential legal issues.

10. Content that promotes hate or violence. Websites that promote hate, violence, or illegal activities should be inaccessible to maintain a safe and respectful workplace.

How to block websites on a network: 5 simple ways

Nowadays, having free access to the internet at work can result in decreased productivity and higher risks to security. This is why it’s important for businesses to find ways to limit access to certain websites.

By combining technical methods and clear rules, companies can ensure their employees stay on task, and their networks are safe. Here are five easy-to-understand ways to do this.

DNS filtering

DNS filtering is a powerful approach to prevent access to specific websites. It blocks DNS queries, which is how the internet translates website names into IP addresses.

When a company sets up DNS filtering, it stops these queries for unwanted websites. This means if an employee tries to visit a non-work-related site, the DNS filter will block it.

Think of DNS filtering like a librarian who decides which books are okay to check out. This method inspects the internet’s ‘book catalog’ (DNS queries) and only lets through the requests for websites that the company thinks are okay. If an employee tries to visit a banned site, the ‘librarian’ simply says, ‘This book is not available.’

This method is effective not only for blocking certain sites but also for preventing access to malicious or phishing sites.

Web filtering software

Web filtering software allows businesses to define which websites are not allowed and enforce these rules across the network. Categories like social media, entertainment, or adult content can be restricted.

The software examines the content of web pages and blocks them if they match the prohibited criteria. This ensures employees access only work-related sites.

Router settings

Routers, especially those for business use, often have features to block specific websites. Administrators can enter URLs or keywords related to unwanted websites through the router’s settings.

This method is especially handy for small businesses without the means for more advanced filtering. It’s a bit like making a no-entry list, but it might need updates now and then to keep up.

Firewall configurations

Configuring firewalls to block websites is like having a guardian at the gate that only lets in traffic that follows the rules set by the business. By blocking specific IP addresses or domains, the guardian ensures that only safe and approved content can be entered.

This method, when used with others, strengthens the security. It can be either a hardware or a cloud firewall, so businesses are flexible in protecting the network.

Browser extensions

Install browser extensions that block access to specified websites on individual devices. While this method applies at the device level rather than the network, it’s a straightforward way to prevent access to non-work-related content on company computers.

Besides technical measures, educating employees about the significance of web filtering and the rationale for blocking certain sites is crucial. This education might include training, policies, or regular reminders about proper internet use at work.

Should companies restrict internet access?

Deciding if companies should limit internet access at work is all about finding the right balance. Many companies block websites that are unrelated to work to keep the workplace productive and focused. However, cyber-attacks are a more solid reason.

In July 2023, Google decided to restrict some employees from accessing the internet, except for Google’s own sites and a few essential services. This was part of an experiment to see how well blocking access could protect against cyber threats.

As the use of AI tools grows and brings more risks to data privacy, and as companies like Google aim for high-security government contracts, the reasons to restrict internet access become even stronger.

Limiting internet access can be a crucial step for companies that handle sensitive information or want to safeguard national security. It helps prevent unauthorized access to websites, ensuring the company’s and users’ data stays safe.
